Class Overview

A ViewStub is an invisible, zero-sized View that can be used to lazily inflate layout resources at runtime. When a ViewStub is made visible, or when inflate() is invoked, the layout resource is inflated. The ViewStub then replaces itself in its parent with the inflated View or Views. Therefore, the ViewStub exists in the view hierarchy until setVisibility(int) or inflate() is invoked. The inflated View is added to the ViewStub's parent with the ViewStub's layout parameters. Similarly, you can define/override the inflate View's id by using the ViewStub's inflatedId property. For instance:

     <ViewStub android:id="@+id/stub"
               android:inflatedId="@+id/subTree"
               android:layout="@layout/mySubTree"
               android:layout_width="120dip"
               android:layout_height="40dip" />

The ViewStub thus defined can be found using the id "stub." After inflation of the layout resource "mySubTree," the ViewStub is removed from its parent. The View created by inflating the layout resource "mySubTree" can be found using the id "subTree," specified by the inflatedId property. The inflated View is finally assigned a width of 120dip and a height of 40dip. The preferred way to perform the inflation of the layout resource is the following:

     ViewStub stub = (ViewStub) findViewById(R.id.stub);
     View inflated = stub.inflate();

When inflate() is invoked, the ViewStub is replaced by the inflated View and the inflated View is returned. This lets applications get a reference to the inflated View without executing an extra findViewById().

The inflated layout resource.

public void setInflatedId (int inflatedId)

Defines the id taken by the inflated view. If the inflated id is NO_ID, the inflated view keeps its original id.

Related XML Attributes

android:inflatedId

Parameters

inflatedId	A positive integer used to identify the inflated view or NO_ID if the inflated view should keep its id.

public void setLayoutResource (int layoutResource)

Specifies the layout resource to inflate when this StubbedView becomes visible or invisible or when inflate() is invoked. The View created by inflating the layout resource is used to replace this StubbedView in its parent.

Related XML Attributes

android:layout

Parameters

layoutResource	A valid layout resource identifier (different from 0.)

public void setOnInflateListener (ViewStub.OnInflateListener inflateListener)

Specifies the inflate listener to be notified after this ViewStub successfully inflated its layout resource.

Parameters

inflateListener	The OnInflateListener to notify of successful inflation.

public void setVisibility (int visibility)

When visibility is set to VISIBLE or INVISIBLE, inflate() is invoked and this StubbedView is replaced in its parent by the inflated layout resource.

Parameters

visibility	One of VISIBLE, INVISIBLE, or GONE.

Protected Methods

protected void dispatchDraw (Canvas canvas)

Called by draw to draw the child views. This may be overridden by derived classes to gain control just before its children are drawn (but after its own view has been drawn).

Parameters

canvas	the canvas on which to draw the view

protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec)

Measure the view and its content to determine the measured width and the measured height. This method is invoked by measure(int, int) and should be overriden by subclasses to provide accurate and efficient measurement of their contents.

CONTRACT: When overriding this method, you must call setMeasuredDimension(int, int) to store the measured width and height of this view. Failure to do so will trigger an IllegalStateException, thrown by measure(int, int). Calling the superclass' onMeasure(int, int) is a valid use.

The base class implementation of measure defaults to the background size, unless a larger size is allowed by the MeasureSpec. Subclasses should override onMeasure(int, int) to provide better measurements of their content.

If this method is overridden, it is the subclass's responsibility to make sure the measured height and width are at least the view's minimum height and width (getSuggestedMinimumHeight() and getSuggestedMinimumWidth()).

Parameters

widthMeasureSpec	horizontal space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
heightMeasureSpec	vertical space requirements as imposed by the parent. The requirements are encoded with View.MeasureSpec.
